Our team advises you to apply the DR.CEURACLE Cica Regen Waterproof Sun SPF50 PA++++ as the last step of your skincare routine, on clean and dry skin. Spread a generous and even amount on the face, neck, and sun-exposed areas, 20 minutes before exposure. Reapply every 2 to 3 hours, especially after swimming, sweating, or wiping yourself.
